EDWARD EVANS, OF QUINCY, ILLINOIS.

STOVE-Ll D PATTERN.

SPECIFICATION forming part of Letters Patent No. 374,147, dated November 29, 1887.

Application filed August 29, 1887. Serial No. 248,206. (ModeLl To aZZ whom. it may concern.-

Beitknown that I, EDWARD EVANS, a citizen of the United States, residing at Quincy, in the county ofAdams and State of Illinois, have invented a new and useful Pattern for the Molding of Stove-Lids of which the following is a specification.

My invention relates to an improvement in patterns for the molding of stove-lids in which slides are used to make the impressions for molding the projections in the coreseat. I accomplish this object by the mechanism illus trated in the accompanying drawings, in which- A Figure 1 is a face view of the pattern with the slides pushed out into the core-seat as they are when the impression is taken; Fig. 2, a back view of thepattern when the slides are in the core-seat as before; Fig. 3, a sectional view of the pattern. Fig. 4 is a detail plan view, one of the plates b being removed. Fig. 5 is a detail sectional view taken through one of the slides.

Similar letters refer to similar parts throughout the several views.

a is the core-scat, in which the hook is placed to raise the lid.

1) b are plates dovetailed into the face of the pattern and made to slide out into the coreseat for the purpose of cleaning out the place or ways in which the slides work. i

c c are the slides.

11 d are the pins to draw the slides outwith.

The slides c c are made with shoulders h, as may be seen in Fig. 3, which work under the plates 1) b and in slots in the pattern and abut against walls of the slots to keep the slides from being drawn out too far.

g g are plates riveted on the under side of the pattern to hold the slides in place.

The slides are pushed out into the coreseats, as seen in Fig. 1, as far as the pins (1 d will allow, and the face impression of the pattern is made in the sand. The mold and pattern are then inverted and the slides drawn out until the shoulders h strike the iron under the plates 1) b. The pattern may then be lifted out of the sand mold.

I am aware that prior to my invention stovelids have been molded by patterns having slides working into the core-seat.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

A stove-lid pattern having acore-seat and a way, a pin arranged in the way and adapted to be projected into and out of a core-seat, and a removable cover for the way.
